e. Starter
The starting motor is lubricated at assembly and should be relubricated only when the starter is
removed from the engine or when disassembled. Remove pipe plugs on outside of motor and
apply a few drops of light engine oil to the oil wicks.
5. Air Cleaner Service
The air cleaner is a dry type with replaceable filter cartridges. A definite time schedule for changing the
filter cartridge cannot be determined because of varying operating conditions. Change the filter
cartridge when the red indicator “flag” reaches the top of the viewing chamber and locks in that position.
Change the cartridge as follows:
a. Cartridge Removal (See Fig. 4)
(1) Open canopy door.
(2) Remove clamp assembly (3) from air cleaner
(3)
Remove baffle assembly
(7).
(4) Remove primary element (4), and replace with new element.
(5) Inspect the interior of the cleaner housing (1). Make certain it is free from all foreign material.
b. Cartridge Installation (See Fig. 4)
Do not clean or re-use cartridge.
(1)
Carefully install the new cartridge into the housing. Avoid bumping the cartridge tubes against
the housing sealing flange. Seat the cartridge properly within the housing. Press all edges and
corners of the cartridge firmly with fingers to effect a positive air seal against the sealing flange
of the housing.
